fix: file read buffer overflow (#13392) 
This PR fixes a heap buffer overflow in `lean_io_prim_handle_read` that
was triggered through an
integer overflow in the size computation of an allocation. In addition
it places several checked
arithmetic operations on all relevant allocation paths to have potential
future overflows be turned
into crashes instead. The offending code now throws an out of memory
error instead.

Closes: #13388
